BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a heat-dissipating base structure and a method for manufacturing the same, and in particular to a heat-dissipating base structure which has a reduced weight and cost and a method for manufacturing the same.

2. Description of Prior Art

With the advancement of technology in the electronic industry, the volume of each chip (such as a central processor) is decreased. However, in order to make each chip to process more data, several times of electronic elements can be mounted in a chip of the same volume than before. When there are more electronic elements in a chip, the amount of heat generated during the operation of the electronic elements gets greater. For example, the heat generated during the operation of a central processor may burn down the whole central processor. Thus, it is an important issue to provide a heat-dissipating device for various chips.

Please refer to FIG. 1, which shows a conventional heat-dissipating base structure 1 including a base 10 and a heat pipe 11 combined with the base 10. The base 10 is often made of metallic materials. Thus, the whole heat-dissipating base structure 1 has a larger weight. On the other hand, the heat-dissipating base structure 1 made of metallic material is more expensive than one made of other materials, which inevitably raises the total cost of the heat-dissipating base structure 1.

According to the above, the conventional heat-dissipating base structure has the following problems: (i) larger weight, and (ii) higher cost.

Therefore, the present Inventor and those skilled in this industry aim to solve the problems in prior art.

One side of the heat pipe is in flush with the open side.

The present invention further provides a method for manufacturing a heat-dissipating base structure, including steps of:

providing a base and at least one heat pipe, the base having at least one trough and made of polymeric materials; and

DETAILED DESCRIPTION OF THE INVENTION

The above objectives and structural and functional features of the present invention will be described in more detail with reference to preferred embodiment thereof shown in the accompanying drawings

FIGS. 2A and 2B are an exploded perspective view and an assembled perspective view showing the heat-dissipating base structure according to the first embodiment of the present invention respectively. As shown in the figures, the present invention provides a heat-dissipating base structure 2 including a base 20 and at least one heat pipe 21. The base 20 is made of polymeric materials. The polymeric materials may be any one of plastics, rubber and plastic compounds.

One side of the base 20 is provided with at least one trough 201. The trough 201 has an open side 2011 and a closed side 2012. The heat pipe 21 is fixedly provided in the trough 201 in such a manner that one side of the heat pipe 21 is in flush with the open side 2011.

The heat pipe 21 and the base are in a tight fit by a machining process. The heat pipe 21 is in flush with the open side 2011. The machining process may be achieved by a punching process.

With the combination of the base 20 made of polymeric materials and the heat pipe 21, the weight of the heat-dissipating base structure 2 can be decreased greatly. Further, the problem that the conventional heat-dissipating base structure made of metallic materials has a larger cost can be solved.

FIGS. 3A and 3B are an exploded perspective view and an assembled perspective view showing the heat-dissipating base structure according to the second embodiment of the present invention respectively. The relationship among the elements of the heat-dissipating base structure of the second embodiment is substantially the same as that of the first embodiment, so that the redundant description is omitted for simplicity. The difference between the second embodiment and the first embodiment lies in that: the heat pipe 21 further has a first side 211 and a second side 212. When the heat pipe 21 is combined with the base 20, the first side 211 of the heat pipe 21 is in flush with the open side 2011. The second side 212 is bonded to the closed side 2012 to thereby combine the heat pipe 21 with the base 20. The bonding is achieved by adhesive.

Since the heat pipe 21 is bonded to the base 20 made of polymeric materials, the weight of the heat-dissipating base structure 2 can be decreased greatly, and the cost thereof can be also reduced.

Please refer to FIG. 4 together with FIG. 2A. FIG. 4 is a flow chart showing the method for manufacturing a heat-dissipating base structure according to the first embodiment of the present embodiment. As shown in this figure, the method of the present invention includes the following steps.

Step S1: providing a base and at least one heat pipe, the base having at least one trough and made of polymeric materials.

In the step S1, a base 20 and at least heat pipe 21 are provided. The base 20 is provided with at least one trough 201 and made of polymeric materials. The polymeric materials may be any one of plastics, rubbers or plastic compounds.

Step S2: disposing the heat pipe in the trough, and applying a force to make the heat pipe to be in flush with one side surface of the base.

In the step S2, the heat pipe 21 is disposed in the trough 201. A force is applied to the heat pipe 21, so that the heat pipe 21 is in flush with one side surface of the base 20. The heat pipe 21 and the base 20 are in a tight fit by a machining process such as a punching process.

By the method of present invention, the base 20 made of polymeric materials can be tightly combined with the heat pipe 21. Not only the weight of the heat-dissipating structure 2 can be decreased greatly, but also the cost of heat-dissipating base structure 2 of the present invention is cheaper than that of the conventional heat-dissipating base structure made of metallic materials.

Please continue to see FIG. 4 together with FIG. 3A. The trough 201 further has an open side 2011 and a closed side 2012. The heat pipe 21 further has a first side 211 and a second side 212. The first side 211 is in flush with the open side 2011. The second side 212 is bonded to the closed side 2012. The bonding may be achieved by adhesive. Since the heat pipe 21 is bonded to the base 20, the weight of the heat-dissipating base structure 2 is decreased greatly. Further, the problem that the cost of the conventional heat-dissipating base structure made of metallic materials is larger can be solved.

According to the above, the present invention has the following advantageous features: (I) smaller weight; and (II) lower cost.

Although the present invention has been described with reference to the foregoing preferred embodiments, it will be understood that the invention is not limited to the details thereof.
